Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to an intelligent gasket structure. Background Art

[0002] A gasket is a small accessory used for filling and thickening, usually located between a bolt and a nut to increase the friction of the fastener, prevent loosening and oil leakage. It is usually circular or square and is made of various materials such as rubber, metal and plastic. According to its materials and uses, gaskets can be classified into the following categories: 1. Metal gaskets: Usually used in occasions with high requirements for high temperature, high pressure and wear resistance, such as automobile engines, engines, axles, etc. 2. Rubber gaskets: Usually applicable to occasions with low temperature, low pressure and large vibration, such as water pumps, air conditioners, braking systems, etc. 3. Plastic gaskets: Usually used for corrosive media and bearing supports.

[0003] Gaskets are commonly used in many mechanical manufacturing and construction projects. The following are some common application scenarios: 1. Automobile manufacturing: As an important accessory for automobile engines, axles and transmission systems, gaskets are used to prevent oil leakage and improve the tightness of fasteners. 2. Mechanical manufacturing: As a necessary component in mechanical equipment fasteners, gaskets are used to adjust the installation accuracy, reduce friction and vibration. 3. Construction industry: In the installation of buildings and structures, gaskets are used to balance and adjust the height and weight of materials, and prevent water and gas penetration.

[0004] The gaskets in the prior art are made of the same material as a whole, do not have the function of sensing pressure, cannot sense the pressure received in real time, and have a low degree of intelligence, so it is impossible to detect in time the looseness between the nut and the bolt, which poses a safety hazard. Therefore, it is necessary to study a solution to solve the above problems. Content of the Utility Model

[0005] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide an intelligent gasket structure, which can solve the problem of low intelligence degree caused by the inability of the existing gasket to sense the pressure received in real time.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An intelligent gasket structure includes a lower gasket body, a pressure sensor and an upper gasket body; a first through hole for the bolt to pass through is opened in the center of the lower gasket body; the pressure sensor is annular, the pressure sensor is superposed and fixed on the upper surface of the lower gasket body, and the pressure sensor has a second through hole for the bolt to pass through, and the second through hole is vertically and oppositely communicated with the first through hole; the upper gasket body is superposed and fixed on the upper surface of the pressure sensor, and a third through hole for the bolt to pass through is opened in the center of the upper gasket body, and the third through hole is vertically and oppositely communicated with the second through hole.

[0008] As a preferred solution, the first through hole, the second through hole and the third through hole are coaxially arranged and are all circular holes, and the inner diameters of the first through hole, the second through hole and the third through hole are all the same.

[0009] As a preferred solution, the outer contours of the lower cushion body and the upper cushion body are both circular, and the outer diameter of the lower cushion body is the same as the outer diameter of the upper cushion body.

[0010] As a preferred solution, the outer contour of the pressure sensor is circular, and the outer diameter of the pressure sensor is smaller than the outer diameter of the lower cushion body.

[0011] As a preferred solution, both the lower cushion body and the upper cushion body are made of metal.

[0012] As a preferred solution, the outer side surface of the pressure sensor has a connecting wire, and the connecting wire extends outwards.

[0013] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0014] This product is composed of a lower cushion body, a pressure sensor and an upper cushion body. The pressure sensor is clamped between the lower cushion body and the upper cushion body. The pressure sensor can be used to sense the pressure received by this product in real time. When the sensed pressure becomes smaller, it indicates that the nut and the bolt are loose. The degree of intelligence has been effectively improved, and it is possible to timely detect the looseness between the nut and the bolt, avoid potential safety hazards, and bring convenience to use.

In this embodiment, the outer contour of the pressure sensor 20 is circular, and the outer diameter of the pressure sensor 20 is smaller than the outer diameter of the lower cushion body 10. The second through hole 21 is a circular hole. And, an outer side surface of the pressure sensor 20 has a connecting wire 22, and the connecting wire 22 extends outwards so as to be electrically connected with an external control circuit. In addition, the thickness of the pressure sensor 20 is greater than the thickness of the lower cushion body 10, and the pressure sensor 20 is superposed and fixed with the lower cushion body 10 by means of glue bonding, or can be fixed by other means, which is not limited.

[0027] The upper cushion body 30 is superposed and fixed on the upper surface of the pressure sensor 20, a third through hole 31 for a bolt to pass through is formed in the center of the upper cushion body 30, and the third through hole 31 is vertically and oppositely communicated with the second through hole 21. In this embodiment, the upper cushion body 30 is made of a metal material, such as a steel sheet, etc., the outer contour of the upper cushion body 30 is circular, the third through hole 31 is a circular hole, and moreover, the first through hole 11, the second through hole 21 and the third through hole 31 are coaxially arranged, and the inner diameters of the first through hole 11, the second through hole 21 and the third through hole 31 are the same. In addition, the outer diameter of the upper cushion body 30 is the same as the outer diameter of the lower cushion body 10, and the thickness of the upper cushion body 30 is the same as the thickness of the lower cushion body 10.

[0028] The usage method of this embodiment is described in detail as follows:

[0029] In use, after the bolt passes through the fixing hole of the external mechanism, this product is sleeved on the bolt. The bolt sequentially passes through the first through hole 11, the second through hole 21, and the third through hole 31 and extends upward.

Next, the connecting wire 22 is electrically connected to an external control circuit, and the pressure received by the pressure sensor 20 can be obtained in real time through the external control system. When the pressure sensed by the pressure sensor 20 is less than the preset value of the control system, it indicates that the connection between the nut and the bolt may be loose, and timely maintenance and repair are required to avoid potential safety hazards.
